Les mondes d'hier : Voyage aux origines de la Terre (Essais Etranger)

Halliday's storytelling makes deep time feel alive, but I wonder if this was planned from the start or developed during research.

The book spans hundreds of millions of years, and I’m curious if readers felt the pacing helped or hindered their understanding of such vast timescales.

The selections felt very intentional, but I wonder what influenced those choices—was it based on significance, available evidence, or narrative flow?
